All MacBook models have two memory user accessible memory slots with support for up to 2GB (2048MB) maximum. Apple recommends that memory be installed in matched size pairs for maximum performance. With a matched pair installed, Apple notes that both memory banks can be accessed at the same time for a maximum memory throughput of up to 10.7GBps.

All OWC Memory is covered by a Lifetime Advance Replacement Warranty and 30 Day Money Back Guarantee! This warranty shows our commitment and confidence in the product we sell. OWC certifies and tests ALL OWC memory to ensure that this memory meets or exceeds the specifications for those systems a module is listed as being correct/compatible with. Unlike the competition, OWC owns and maintains our own lab that includes nearly every Apple/Mac model we list compatibility for.
In addition to the long testing every OWC module undergoes before shipping (which goes well beyond industry standard 'short testing'), we also continuously batch test modules in the actual systems they are offered for. You can count on OWC to consistently deliver the top quality memory products you need, correct for your system for a lifetime of reliable operation. Click
